Last week, I gave a presentation on accessible touch objects in partnership with my colleague Lauren Race from the NYU Ability Project. Our talk was part of the MCN2020 virtual conference. Here are the highlights and links for further reading.
Defining the problem
Most information at museums and historic sites is presented visually, but some people learn through tactile exploration. For accessibility, we need to be considering all senses when presenting information at museums.
Yet, tactile access has faced looming threats, notably the lack of expertise and funding, before Covid-19, and the current pandemic is accelerated these issues.
Some museums have responded to Covid-19 by closing hands-on exhibits with tactile components. For example, the Please Touch Museum extended its closure into 2021.
Knowing that touch objects are threatened, it is important to determine which are worth saving in the future.
Summarizing the research
Lauren described interviews that she conducted with 15 museum access specialists from art museums and historic sites across the United States. Then she considered common themes from their responses in conversations with 6 accessibility experts who are blind or have lo vision.
There are 4 findings.
• 1. Tactile experiences must be preserved
• 2. They should be consistently created
• 3. They read as infantile when poorly-crafted
• 4. They cannot be replaced by audio (verbal description) or digital-only solutions. People who are blind receive touchless experiences secondhand, filtered through the observations of a sighted person.
Recommendations
We made the following recommendations.
•Tactile experiences must be preserved
•Digital fabrication over poorly-designed techniques
•Provide tactually accurate reproductions
•Choose materials that can withstand frequent cleaning
•Establish tactile design guidelines
For my section of the presentation, I discussed ways to preserve tactile access despite Covid-19. I described my other projects that complimented Lauren’s interview findings.
People are problem solving in the moment. When the pandemic began, I had ongoing conversations with tactile artists about ways to safeguard tactile access.
Two colleagues, Ann Cunningham, and Matt Gesualdi and I identified specific examples drawn from our work that we proposed as models for safe practices during the Covid-19 pandemic. We described this work in a blog post for the American Alliance of Museums.
Staying in touch: addressing concerns to allow tactile exploration at museums
I will summarize with this quote.
“We imagine a scenario where visitors could borrow tactile handouts, use them for reference as they tour an exhibit, and then return them to the museum for treatment and later re-use.”
That blog post included photos of small- and large-scale examples of tactile handouts. At small scale, the 3D-printed replica of a stone spear point can be manipulated with one hand. The attached wooden coin is a QR code that when scanned directs a smartphone to read more information about it such as might be found on an exhibit label.
At larger scale, people can be encouraged to maintain physical distance as they explore separate tactile panels. This idea is loosely based on an interactive art installation titled “Mission to Nocterra,” created by Matt Gesualdi. He incorporated use of antibacterial wipes into the exhibit with a story line that the puzzles were alien artifacts that must be protected from human germs.
Highly-skilled tactile artists can create accurate tactile reproductions using hand-crafted techniques. These individuals plan and construct their work very carefully and they account for scale and accuracy. With questions of high-fidelity in mind, we ranked different techniques by their cost in the same blog post.
Returning to Lauren’s interview findings, we recommend digital fabrication methods such as 3D printing over poorly-designed, hand-crafted techniques. In our opinion, digital fabrications are preferred for the accuracy of tactile reproductions. This is contrasted with the analog nature of most poorly-designed tactile objects that her interview findings indicated were produced by interns or volunteers with no training in tactile design.
Due to Covid-19 and safety concerns, we recommend fabricating touch objects from materials that can withstand frequent cleaning. This would favor plastic or acrylic resin commonly used to fabricate 3D-printed replicas.
We mentioned other work that supports accessible touch objects. Fortunately, we are not the only people seeking ways to safely conduct tactile exploration. Here is an international example.
Tactile Studio posted their proposed solutions including the development of a tactile sanitation station for touch objects.
I am encouraged by these proposed solutions because the work to preserve access to tactile objects in museum exhibits is ongoing and it will require sustained efforts in the Covid-19 era and beyond.
